Antibiotics you throw away may be breeding superbugs

NEW DELHI: Tonnes of antibiotics, painkillers and different medications are flowing down the Yamuna, and scientists at AIIMS say our addiction of throwing away leftover medications in household garbage is partly accountable for this.

The drugs could be coming back to us in milk, vegetables and different agricultural produce, and also giving upward thrust to superbugs that almost all antibiotics can't kill.

In 2015, researchers from AIIMS’ ocular pharmacology department began studying pharmaceutical contamination in the Yamuna to provide an explanation for the emergence of superbugs.

The group, headed by Dr T Velpandian, analysed water samples from seven puts along the river, including its access and go out points in the city, 35 bore wells in Delhi NCR and water percolating thru waste on the Ghazipur landfill. They found the focus of dissolved drugs increased manifold along the Yamuna’s course.

At its access near Wazirabad in north Delhi, concentrations of fluconazole (antifungal), ofloxacin (antibiotic) and ibuprofen (painkiller) were lower than 0.05 micrograms consistent with litre.

A microgram is a millionth of a gram, so 20 million litres of river water contained 1g or much less of these drugs. The painkiller diclofenac used to be found in double energy — 0.1 microgm a litre.



‘Drug concentrations alarmingly prime in groundwater near Ghazipur landfill'

The unused drugs that you get rid of without a 2nd concept could be coming back to you in milk, vegetables and different agricultural produce.

At the Yamuna’s go out near Okhla barrage, the concentrations of fluconazole, ofloxacin and ibuprofen increased by 80, 96 and 50 times, respectively. Diclofenac increased by 121 times. The group’s findings have been printed in the latest version of the magazine Environmental Science and Pollution Research.

To find out the resources of air pollution, the researchers tested groundwater samples and also the water percolating from the Ghazipur landfill. “We found alarming drug concentrations towards the area adjoining to Ghazipur landfill,” Dr Velpandian stated.


“This means that a large number of unused drugs, expired or now not, are thrown into dustbins, finally end up on the landfill, and from there percolate into the local drains and finally finally end up in the Yamuna.”


He stated Delhi and different densely populated spaces desire a strict policy for setting apart and destroying bioactive compounds in order that they don't accumulate in the atmosphere.


“We suggest continuous monitoring for bioactive compounds in water assets and developing consciousness on disposal of unused or expired medications thru responsible organisations.”


L Moksha, co-author of the learn about, stated that during some advanced nations unused drugs need to be returned to pharmacies and they're incinerated. People throw away expired medications thinking they're useless however “they're still active although their efficiency may have diminished”.
